PRINTING DEVICE.

Specification of Letters Patent.

Patented Dec. 20, 1910.

To all 'whom t may concern: v

Be it known that we, RUSSELL H. BREWER,

ODEN F. Tami', and STEPHEN I-IoLLANDs, citizens of the United States ofAmerica, residing at Reading, in the county of Berks and State ofPennsylvania, have invented neu7 and useful Improvements in FrintingDevices, of which the following is a specification.

This invention relates to printing attachments for paper roll holders,and it has for an object to provide an attachment of this character thatcan be conveniently applied to the roll holder.

Another object of the invention is to provide a novel form of springtension or controlled roll carrier for supporting the printing roll, theinking roll and the reservoir and to provide a stop member which isoperable to bear against the carrier to limit the movement thereof inone direction.

A still further object of the invention is to provide a hood coveringthe printing roll, the inking roll and the reservoir, constructing thehood to provide gutters or receptacles for receiving any surplus inkwhich may be discharged from such rolls.

In the drawings, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several viewsz-Figure 1 is an end view of a roll and roll holder showing our improvedinking attachmentl applied thereto, the said attachment being shown insection and parts of the holder being shown in section to clearlyillustrate the invention. Fig. 2 is a front elevation of the roll holder.and the printing attachment, parts being shown in section for thepurpose of clearness. Fig. 3 is a. detail longitudinal section throughthe reservoir. Fig. 4 is a detail perspective view of the hood. Fig. 5is a detail perspective lView of the stop member. Fig. 6 is a detaillongitudinal section through a slightly modified form of reservoir.

The holder for the roll of paper forms no particular part of theinvention but it will be brieiy described as consisting of a pair ofspaced standardsAwhich are connected with each other at their upper endsby horizontal brace rods B and C, the latter supporting a knife D whichmay be of any approved well known construction. At the lower ends thestandards A are connected together by brace rods E and F. The standardsA are formed to provide horizontal bearings G for the reception of theends of the supporting shaft H for the roll of paper I.

Ourimproved inking attachment consists of a frame comprising companionspaced members 1 which are curved upwardly and rearwardly from the backof the roll I having their lower ends pivotally mounted on the brace rodF so that the frame is movable toward or away from the said roll I. Themembers 1 are connected with each other by suitable brace rods 2 and asshown, to one of such rods is secured the outer terminals of springs 3,the inner terminals of the said springs being secured or suitablyassociated with the brace rod E so that the tension of the springs is tonormally hold the printing roll 4 yieldingly engaged with the roll I.

The members 1 are formed to provide the bearing recesses 5 for receivingthe trunnions 6 of the printing roll. This roll is formed at its ends toprovide collars 7 against which the ends of the inking roller 8 areengaged. The upper extremities of the members 1 are forked to formbearing recesses for the trunnions of the inking roll and as shown,these recesses are so formed that the inking roll frictionally bearsagainst the printing roll.

The inking roll is covered approximately throughout its length withabsorbent material 9 of any suitable well known character, the ends ofthe surface formed by such material being disposed directly between thecollars 7 of the printing roll. The recesses vformed at the upper endsof the members 1 also receive the trunnions 10 and`11 of a reservoir 12.This reservoir is in form of a cylinder whose walls are formed toprovide rolls of suitable perforations or feed openings 13. The saidreservoir is covered approximately throughout its length with suitableabsorbent material 14L which may be saturated sufficiently to distributeonto the inking roll the desired quantity of ink. The trunnion 11 of thereservoir is formed at the closed end 15 thereof and the trunnion 10 isformed at the end of a cap 16 which ity with inl; as will be understood.On rei ,inoval of such reservoir it is obvious that the cap 1G thereofcan be removed for the purpose of filling such reservoir. The members lare provided with pins 2O to which the lower ends of retractile springs21 are attached. The upper ends of these springs are suitably secured tothe trunnions 10 and 1l of the reservoir. rlhe springs as described. aresuch that the rollers 4- and S are yieldingly engaged with each other.rlhe construction is also such that the reservoir is yieldingly engagedwith the inling roll.

A hood Q2 is employed for housing the rolls Lili, S and l2 and as shown,the said hood is formed to provide a forwardly and downwardly directedfront portion 23 and a forwardly and downwardly directed bach portionQet. The edge at the lower end of the front portion S23 is formed toprovide a trough or receptacle 25 which is located between the rolls el,and 8 and slightly in ad- Vance thereof. T he lower edge of the portionelis formed to provide a similar re ceptacle or trough 26. These troughsare designed for the reception of such surplus ink that may bedischarged from the rolls onto the hood. The hood is preferably securedin place by means of suitable fastening screws Q7 which are engaged withthe members l.

To limit the swinging movement of the roll-carrying frame of ourimproved. attachment we provide a stop member 2S which is pivotallymounted on the brace rod F. This stop member is formed with a notchedforward portion 9.9 which receives the brace rod E. The said stop memberis formed to provide an ear 30 which is curved transversely and disposedacross the upper surface of one of the side members l at the lower endthereof, the edge 3l of the said ear being designed to engage such sidemember so as to limit the .movement thereof toward the shaft H of theroll l. In this construction it will be readily understood that when thepaper is entirely removed from the axle the carrier formed by themembers l will be held against coming in direct cont-act with said shaftH. llt may be mentioned that the shaft ll is provided atits ends withremovable cotter pins J which serve to hold the cones K operativelypositioned in the roll and against longitudinal movement on the shaft,thus insuring a perfect engagement o f the printing roll wit-h the paperat all times.

In the modified form of ouiI invention shown in Fig. G, the reservoir 32is formed at one end to provide an interiorly threaded portion 33 toreceive the eXteriorly threaded portion of cap Bil. This cap isinteriorly threaded to receive the eXteriorly threaded surface of thereduced end 35 of a hollow cylindrical valve This valve is designed forthe reception of the ink and through the provision of the passages 37 inthe valve the desired quantity of ink will be permitted to tlow from thepassages 38 onto the absorbent surface 39. The closed end of thereservoir is provided with a cylindrical l earing el through whichextends the stem This stein extends from the head t3 of the valve and asillust-rated, it is formed with a manipulating knob llt. It will beunderstood that upon rotation of the stem il?. the valve may rotated andmoved longitudie nally to a slight extent in thc reservoir to cause theopenings 3T and 38 to move into or out of registration with each other.

Wie claim In a printing device for paper roll holders, the combinationwith a roll holder having a pair of horizontally disposed rods which arelocated beneath the roll, a printing roll, a carrier therefor havingpivotal connection with one of the said rods of the roll holder, springmeans operatively connecting the other rod with the carrier for holding`the printing roll yieldingly engaged with the paper roll, and a stopsupported by one of the rods and designed to engage the carrier to limitthe movementthereof in one direction.

In testimony whereof we atlix our signatures in presence of twowitnesses.
